Description
Technical Field
The invention relates to a computer technology, in particular to a building drawing three-dimensional data processing and three-dimensional modeling display technology and an automatic die matching technology based on the internet.
Background
The traditional building engineering generally uses wooden templates and steel templates to carry out pouring operation to complete construction, namely, the wooden or steel templates are surrounded to form a formwork and then concrete pouring is carried out, and after the concrete is cured, the relevant templates are dismantled to realize the reuse of the templates. In some areas and cities, the assembly method is also adopted for building construction, namely the whole building is disassembled according to modules, the production of each module is completed in a factory, the modules are transported to a working face for assembly, and the concrete at key connecting parts is cast in situ through steel bar lap joint to complete the building construction. In recent time, because the yield of aluminum profiles is increased and the processing cost is reduced, a large number of aluminum templates are adopted for building construction, the basic construction principle and the mode are similar to those of the construction of the traditional wood templates or steel templates, but the aluminum materials are light in weight and high in rigidity, the template reuse rate of high-rise building construction can be improved, the workload of manually disassembling and assembling the templates is reduced, and particularly the conveying cost of transporting the disassembled lower-layer templates to an upper-layer operation surface is reduced.
All these construction techniques and methods, although having certain advantages over earlier more traditional construction techniques and methods, still do not break through the need for very much manual human reading of building and structural construction drawings and the manual conversion of the relevant information into a one-by-one calculation of template position, dimensions, assembly method parameters and the creation of on-site construction lists or lists. The construction drawing is a project drawing drawn according to the principle of orthographic projection and related professional knowledge, and has the main task of representing the internal and external shapes, the plane arrangement, the floor height, the building construction and decoration methods of a house, which are called 'construction' for short, and are the foundation and the guide of various construction drawings and one of the main bases for guiding civil construction. In a word, the building construction drawing is mainly used as a basis for construction paying-off, foundation and wall building, floor slab laying, stairs, roofs, door and window installation, interior decoration, budget planning, construction organization planning and the like. The basic drawings comprise a general construction description, a general plane diagram, a building elevation diagram, a building section diagram, a building detailed diagram, a door and window table and the like. The construction drawing is a project drawing about the arrangement, the used materials, the shape, the size and the internal structure of the load-bearing member, and is the basis for the construction of the load-bearing member and other stressed members. The structure construction drawing comprises the contents of a general structure description, a foundation arrangement drawing, a bearing platform reinforcement layout, a ground beam arrangement drawing, each layer of column reinforcement layout drawing, each layer of beam reinforcement layout drawing, a roof beam reinforcement layout drawing, a stair roof beam reinforcement layout drawing, each layer of plate reinforcement layout drawing, a roof plate reinforcement layout drawing, a stair big sample, a node big sample and the like.
Although the time for the computer aided design technology and method to appear is long enough, the technology and method only stay at the stage of realizing the drawing of the construction drawing or the engineering drawing by the assistant manual work, and the prior art has the defects of long repeated time consumption and extremely high labor cost from the overall engineering point of view. In the occasions of aluminum template building construction or prefabricated building construction, the technical scheme of automatic guiding field construction from the building drawing and the structural drawing is urgently needed to save labor cost, construction cost and the like.
